COMBINED CHARGING AND FEEDING DEVICE FOR GASOLENE-ENGINES.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Applicationfiled August 14, 1808 Serial No. 448,503.

Be' it-known that I, LOUIS W. VITRY, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Combined Charging and Feeding Devices for Gasolene-Engines, of which the following is a specification.

My invention relates to improvements charging andfeeding devices for-gasolene engines, and the objects of my improvements are, first, to provide a sure and rapidlyacting charging device for a gasolene engine,- and second, to so combine the said chargin with a regular feeding device that the latter 4 engine with gasolene-"vapor as soon as said charging device has effected its function of objects I have accomplished by the means which are hereinafter fully described and accompanying drawings, in which:

Figure l is aside elevation of a gasolene engine equipped with my said improved combined charging and feeding device. Fig. 2 is an enlarged detail in partial section, with parts shown broken away, of said charging and feeding device. Fig. 3 is a longitu inal section of the rear part of the engine cylinder, showing the gas inlet chamber-and its retractile valve.

throughout .the several views.

The engine 4 rests on a base 35, and has of the piston 6, the pitman 33, crank-she t 36, and fiy-wheel 34 mounted on said shaft.

The compression-chamber 28 of the cylinder is separated from a rearwater-cooling chamber 32 and an adjoining mixing-chamber 8. A communication between the com pression and mixing chambers is effected by means of an inlet-port 30 covered by a retractile valve 29 whose head is within said compression-chamber and is kept ordinarily over and closing said port'by means of a tension spring 26, the latter being coiled about the end of the'valve-stem outside of the cylinder and bearing against the latter; The air and gas are both introduced into the chamber 8 through an inlet said cylinder wall into which isinserted'the elb'ow' tube 9, the lower end of the latter being ordinaril open to the surrounding atmosphere. I hefopen lower end of the tube 9 dips within but. is spaced away from the bottom and concentric sides of the cup 10', the said cup having a small orifice 23 just above vthe lower edge of said tube 9.

The numeral 1 designates a tank for gasolene whose top should be of sufficient height above the base 35 to afford enough head to the oil; therein that the latter may quickly overcome the friction in the long pipe ,3

such oil in the tank should be high enough as to keep the difierent parts of thefeeding device charged at all times as will be hereinafte'r described.

The pipe 3 leads from the tank 1 to a T- coupling 12, and the latter has a communication with an anglecheck-valve c amber 5,

above it from returning bac intd the pipe 3 and tank 1. The stem 13 of said checkvalve moves in a cylindrical bearing 18 de: pending from the removablecap 17 The valve-chamber 5 communicates with the valve-chamber 31 by means of an'elbowcoupling 37 and pipe 38. The valve-chamber 31 contains a 1"egulatingor throttlevalve 15 for. the gasolene, the said valve chamber 31 communicates with the elbowchamber 2 is inserted in the pipe 3 'to conerated bymeans of a thumb-piece 24,- when it is desired to shut off theflow of gasolene at timeswhen inspection" or repairs of the feeding or charging device is necessary; j

The cup 10 issuspended'from a hangerof the tube 9, and said hanger has openings with the pipe 3 by wayof the T-coup ing- 12, and contains an ordinary-sto -cock 21 adapted to be manually o erated b of the thumb-piece 20. short nozzle.22 leads from said valve-chamber 11 to' and is through one of the openings 27.

the fly-wheel 34 is rotated todraw a charge coulpli'ng'l, and the latter communicates wit 1 both sald chamber 8- and the depending vof mingled gas and air through the port 30, chamber 8, and tube 9. The stop-cocks 25 ring 40 which is secured about the lower end 27 Arable-chamber 11 is'in communicafion adapted to deliver gasolene into the cup 10.

especially in cool weather, and the level of.

- phere,

and 21 having been previously opened, the cup 10 has beenpermittedto fill with gasolene until the gasolene appears at the orifice 23, when the cock 21 is shut ofl. The position of the orifice 23 is such that it permits the level of gasolene in the cup 10 to rise merely to or slightly above the lower edge of the tube 9. As by the means described a charge of gas and'air isdrawninto the cylinder by the moving piston, from the cup 10 and the openings 27 as the air from the openings 27 is sucked through the'gasolene covering the lower end of the tube 9 such airis quickly and thoroughly impregnated with a proper amount of gasolene vapor, which moves into the cylinder through the opened valve 30. The firing of this preliminary charge suffices to start the engine,

which thereafter draws gasolenevapor through the chambers 8, and, 31 from the chamber 5 regularly, and automatically.

Provision is made in the cup 10 for only I enough ga'solene below the orifice, 23 to supply. a preliminary charge, only is drawn through the tube 9 from the openings 27 to mix in the chamber 8 with the vapor drawn thereinto from the chambers 31, 5 and the pipe 3.

It will be seen that this combined device is quickly started, runs thereafter auton'iatically, and dispenses with pumps, floats and overflow cup. I

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A combined charging and feeding device for a gasolene engine, composed in combination with a cylinder and a movable piston therein, said cylinder having an inlet port and retractile means for closing the latter, of a mixing-chamber discharging into said port, a receptacle open to the atmosa tube communicating between said receptacle and said mixing-chamber, a vessel containing a fluid hydrocarbon under a desired amount of head, means of communicaand thereafter air piston therein,

tion between said vessel and said mixingchamber, and between said vessel and said first-mentioned receptacle, and means for regulating the level of the hydrocarbon in said receptacle.

2. A combined charging and feeding device for a gasolene engine, composed incombination with a cylinder and a movable piston therein, said cylinder having an inlet-port and retractile means for closing the latter, of a mixing-chamber discharging into said port, a receptacle open to the atmos phere, a tube communicating between said receptacle and said-miXing-chamber, a vessel containing a fluid hydrocarbon under a desired amountof head, means. of communication between said vessel and said mixingchamber provided-with meansfor the regulation of the passage of the hydrocarbon therethrough, and means ofcommunication between said vessel and said receptacle.

3. A combined charging and feeding device for a gasolene engine, composed in combination with a cylinder and a movable said cylinder having an inlet-port and retractile means for closing the latter, of a mixing-chamber discharging into said port, phere, a tube communicating between said receptacle and said mixing-chamber, said tube having its open end adapted to dip slightly below the level of the content-s of said receptacle, a vessel containing a fluid hydrocarbon under a desired amount of head, means of communication between said vessel and said mixing-chamber, and means of communication between said' vessel and said receptacle, said receptacle being provided with means for regulating the level of its contents.
